Application filed November 3, 1909. Serial No. 526,043.

To all whom it may concern:

Be it known that I, Orro MAR UARDT, joiner, a subject of the GermanEmperor, and residing at Schneidemiihl, Germany, have invented certainnew and useful Improvements in Sifting Arrangements for of'which thefollowing is a specification. i

In flour mills in which the product is l coarse, branny particles orupper edge of said sieve and then sifted in running down due to itsgravity as well as to the vibrations of the sieve being effected by theworking of the machine. The flour will fall to the discharge opening 0While the roats are passed along the sieve to the disc arge opening 6.

Sacks may be attached to the openings in currentkin addition to thecentrifugal force,

the sifting is generally effected by means of oscillating or rotatingsieves,'an arrange ment which, bein complicated, requires much space anddriving power.

The present invention relates to kibbling- "mills or mills forrough-grinding corn,

which are considerably simplified in that the greats being thrown fromthe millstones to the discharge as described above, are conducted to theupper edge of a stationary resilient sieve arranged in oblique positionin j which sacks the separated products are then passed to the dischargeby means of an air delivered.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is:

In a kibbling-mill, the combination with a cylindrical casing, of a pairof mill-stones vertically arranged in said 1 casing, of a i downwardlycurved outlet connected to said casing and adapted to guide the groundcorn 1 being tangentially forced out of the casing, of a discharge chutesuspended to said out- I let,- of a triangular cross-piece attached to acasing attached to the discharge chute,j

whereupon said groat-s are sifted in passing along the sieve underitsgravity assisted by to the discharge chute in the direction of thearrow. In a casing d, joined to said chute, a resilient sieve a isarranged in oblique positlon. The coarse ground corn 1s fed on the themouth of said discharge chute and adapted to form two dischargeopenings, and of a vibrating sieve obliquely arranged between the inneredge of said-cross-piece and the outer wall of said discharge chute andadapted to cover theouter discharge opening so as to permit the flour tobe forced through it and the coarse, branny particles to be passed alonit to the inner discharge opening, substantially as set forth.

In testimony whereof, I afix my signature in the presence oftwowitnesses.
